TRENTON, N.J. -- Gov. Chris Christie was traveling from San Francisco to Boston when a passenger had to be removed from the plane before takeoff.

Christie spokeswoman Maria Comella said in a statement the Republican presidential candidate, an aide and a member of his security detail were traveling Friday morning from San Francisco to Boston aboard a United Airlines flight when a passenger was removed before takeoff at the airline's request.

Comella says at no point did the governor interact with the passenger, nor did the passenger pose a verbal or physical threat to Christie.

United spokesman Jonathan Guerin says flight 1108 was delayed because of disruptive customer.

It's unclear why specifically the passenger was removed.

Christie's campaign after the delay that a New Hampshire event set for Friday evening would be rescheduled.
